SPECIFICATION formingpart of. Letters Patent No. 754,431, dated March15, 1904.

' Application filed May 14, 1903. Serial No. 157,145. (No model.)

To all whom it may concern.- 1 Be it known that I, J AMES M. CROWLEY, acitizen of the United States, residing at Carl Junction, in thecounty ofJasper and State of Missouri, have invented a new and useful Pump, ofwhich the following is a specification.

The invention relates to improvements in pumps.

The object of the present invention is to improve the construction ofpumps and to pro vide a simple and comparatively inexpensive I balancedpump adapted with a short stroke to lift water acons'iderable distance,whereby it is adapted to be operated within a comparatively small space.7

A further object of the invention is to provide a pump of this characterin which it will be unnecessary to provide a column-pipe and -which willlift water on the downstroke of the lever for actuating thewater-elevating mechanism. 7

With these and other objects in view the inyention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings, and pointedout in the claims hereto appended, itbeing understood that variouschanges in the form, proportion,

size, and minor details of construction within the scope of the claimsmaybe resorted to 'without departing from the spirit or sacrificing anyof the advantages of the invention.

'In the drawings, Figure 1 is a vertical sectional View of a pump.constructed in accord Flg. 2 1s a horizon- Fig. 3 is a deintermediate oftheir ends by bolts 2 or other suitable fastening devices to a support3, which may be constructed in any desired manner and Which is providedwith opposite upright portions 4, having perforations 5 arranged atintervals and adapted to receive the pivots or fulcrums of thelazy-tongs, whereby the latter are adapted to'be adjusted to vary theirlength and to obtain the, desired length of stroke. The lazy-tongs arepreferably formed of alternately-arranged single and double barsorlinks, the single bars or links being arranged between the members ofthe double bars or links; but any other desired arrangement may beemployed for securing the necessary strength.

The upper ends of the lazy-tongs are pivoted to vertical bars or links6, provided at intervals with perforations and adapted to afford anadjustable connection between a walking beam 'or lever 7 and thelazy-tongs. The walking beam or lever 7 is fulcrumed between its ends onthe support 3, at the center of the top thereof, and is provided with anarm 8, which extends upward from the walking beam or lever 7,'as clearlyshown in Fig. 1 of the drawings. The arm 8 is connected by a rod or bar9 with suitable operating mechanism, (not shown,) and when the walkingbeam or lever 7 is oscillated the lazy-tongs will be'alternatelyexpanded and contracted fora purpose hereinafter explained. The bars orlinks 6 permit the distance between the upper ends 4 of the lazy-tongsand the fulcrum point or pivot 2 to be varied, and one or more sets oflinks may be removed, or the number of bars or members of the lazy-tongsframe may be increased. The size of the support 3 and the length of thelinks or bars 6 may be varied, as will be readily understood.

The lower ends of the lazy-tongs are connected with elongated Valvestems or rods 10, which receive buckets l1 and valves 12. The valves,which preferably consist of cylindrical blocks, are secured to the lowerportions of the rods by nuts 13 or other suitable means, and the bucketsare capable of a limited movement on the valve rods or stems independentof the valves. The buckets, which are open at the top and bottom, areprovided at their tops with spiders 14:, having central openings to.receive the valve rods or stems, and the lower ends of the buckets areclosed on the upstroke by the valves, which are secured to the lowerportions of the rods or stems.

Each bucket is provided at opposite sides with upper and lowerantifriction rollers or wheels 15, arranged in pairs, as clearly shownin Fig. 1, and mounted between perforated lugs or cars, which projectoutward from the bucket at diametrically opposite points. Theantifriction rollers or wheels are arranged in grooves 16 of verticalguides 17, which are provided at their upper ends with suitable seats18, adapted to be engaged by the wheels of the bucket or receptacle fora purpose hereinafter explained. The vertical guide-bars, which arelocated at diametrically opposite points, extend downward from a trough20 and project upward a short distance above the same. The trough isprovided at opposite sides with openings 21 to receive the buckets andthe valves, and it has upwardly-extending flanges surrounding theopenings 21 to prevent any water from draining back into the well. Theguide-bars 17 are located in recesses at opposite sides of the openingsof the tank or trough, and the valves, which are preferably cylindrical,but which may be of any other desired configuration, entirely fill theopenings when they are arranged as shown at the left-hand side of Fig. lof the drawings. On the upstroke the valve is carried upward against thelower end of the bucket or receptacle, thereby closing the same andconfining the water within the bucket. The water is held in the bucketby the valve until the bucket arrives at the top of the guide-bars andengages the seats thereof. The bucket is thereby interlocked with theupper portions of the guide-bars, and when the lazy-tongs expand on thedownstroke the bucket remains stationary until the lower end of thelazy-tongs engages it and forces it downward from the'seat. Thevalve-stem 10 is of sufficient length to permit the valve to move awayfrom the bucket and permit the water to escape into the trough 20. Inpractice the upper portions of the guidebars will extend a suflicientdistance above the trough 20, and the movement of the valve independentof the bucket will be ample to allow the contents of the bucket todischarge completely before the valve leaves the opening of the trough.The valve is increased in length, as illustratedin the accompanyingdrawings, in order to permit the necessary movement of the valve throughthe opening of the trough.

The valves are provided at opposite sides with vertical ribs orflanges'22, which slide in the grooves of the guide-bar l7, and theupper portions of the latter are sufliciently resilient to enable thebuckets to be readily engaged with and disengaged from the seats 19; butany other suitable means may be employed for retarding the buckets atthe upper ends of the guide-bars to secure the operation of theapparatus. This structure besides opening the buckets fordischargingtheir contents also insures the opening of the buckets on the downwardmovement of the lazy-tongs to facilitate filling the buckets.

Any suitable means may be connected with the bar 9 for operating thepump, and when the walking beam or lever is oscillated the lazy-tongswill be reversely operated. One of the lazy-tongs will be extended andthe other contracted at each stroke of the walking beam or lever.

The trough 20 is provided with a spout 23; but any other suitable meansmay be employed for conveying the water from the buckets to the pointsdesired.

What I claim is 1.
